FIELD

[0001] The present disclosure provides processes to convert naphtha range hydrocarbons to distillates. The present disclosure further provides compositions including distillates.

BACKGROUND

[0002] As the production of shale and tight oils is increasing in the United States of America, Natural Gas Liquids (“NGL”) and naphtha are becoming increasingly abundant. Ethane to light naphtha range paraffins are largely fed to steam crackers or dehydrogenated to make olefins. For example, ethane is steam-cracked to make ethylene, and light naphtha (b.p. 60°F-160°F) is steam cracked to make ethylene, propylene, and small volumes of dienes. Short-chain alkanes (e.g., C2 to C5 alkanes) can also be converted to their corresponding olefin using dehydrogenation technologies. Dehydrogenation of short-chain alkanes (e.g., C2 to C5) commonly uses one of two types of catalysts: platinum-based catalyst(s) or chromium oxide catalyst(s). The dehydrogenation process is typically carried out at temperatures > 450°C, and under ambient or sub-ambient pressure. To manage the frequency of catalyst regeneration due to coking, reactors such as moving-bed, cyclic swing-bed, or fluidized bed reactors are employed. On the other hand, heavy naphtha (b.p. 160°F-360°F) is typically fed to catalytic reformers in order to produce aromatics (as chemicals or high octane gasoline blend), and hydrogen, but no catalyst/process that selectively dehydrogenates naphthenes to mono-olefins has been described.

[0003] As the reformers reach capacity, coupled with the limited growth in demand for aromatics and gasoline, there is a continuous need to convert heavy naphtha, particularly heavy virgin naphtha (HVN), to large volume, higher value products. Furthermore, global transportation fuels outlook suggests that the long-term demand for automotive gas (e.g., gasoline) will decrease, while the demand for octane is expected to grow with the increasing use of high-compression engines. Conversely, global fast growing demands for distillate (e.g., jet, diesel) favors the conversion of heavy naphtha (low-octane gasoline; e.g., Research Octane Number (“RON”) and Motor Octane Number (“MON”) for cyclohexane are 83.0 and 77.2, respectively; RON and MON for n-heptane are zero) to distillate range liquids.

[0004] Furthermore, the excess in supply of light alkanes and olefins due to shale gas and hydraulic fracturing (also referred to as“fracking”), in addition to traditional light cuts (e.g., C5 of the Fluid Catalytic Cracking,“FCC”), has limited new uses of these products. Hence, growing the molecular weight of light alkanes and olefins into fuel/lubricant ranges would be valuable, particularly due to the lower value of light alkanes, and the higher value of fuels, and lubricant range hydrocarbons.

[0005] Therefore, there remains a need for processes that provide a highly efficient and economical conversion of heavy hydrocarbons to light distillates and/or mid-distillates, such as distillate range liquids, under mild conditions. Furthermore, there is a need for processes to convert heavy naphtha, particularly naphthene-rich heavy virgin naphtha, to distillate range products.

SUMMARY

[0007] In an embodiment, a process for upgrading a hydrocarbon feed includes dehydrogenating a C3-C50 cyclic alkane (e.g., a naphthene), where the ring size is 3 to 8 carbons, and a C2-C50 acyclic alkane in the presence of a dehydrogenation catalyst to form a C3-C50 cyclic olefin and a C2-C50 acyclic olefin. The process includes reacting one or more C3-C50 cyclic olefin and the C2-C50 acyclic olefin via olefin metathesis in the presence of a transition metal catalyst, such as a group 6, 7, or 8 transition metal catalyst, to form larger molecules that contain 2 or more carbon-carbon double bonds (e.g., Cs- C200 olefins, such as C5-C100 olefins). The process further includes hydrogenating the C5-C200 olefins in the presence of a hydrogenation catalyst to form a C5-C200 hydrogenated product (e.g., alkane).

[0008] In another embodiment, a process for upgrading a hydrocarbon feed includes dehydrogenating a C3-C50 cyclic alkane and a C2-C50 acyclic alkane in the presence of a dehydrogenation catalyst to form a C3-C50 cyclic olefin and a C2-C50 acyclic olefin. The process includes reacting the C3-C50 cyclic olefin and the C2-C50 acyclic olefin in the presence of a transition metal catalyst, such as a group 6, 7, or 8 transition metal catalyst, to form larger molecules that contain two or more carbon-carbon double bonds (e.g., C5-C200 olefins, such as C5-C 100 olefins). The process further includes hydrogenating the C5-C200 olefins in the presence of a hydrogenation catalyst to form a C5-C200 hydrogenated product (e.g. alkane). The process further includes hydroisomerizing the C5- C200 hydrogenated product in the presence of a hydroisomerization catalyst to form a C5-C200 hydroisomerized product.

PET ATT /ED DESCRIPTION

[0019] The present disclosure provides C5-C200 hydrocarbon products, such as C5-C100 hydrocarbon products and processes for making such C5-C200 hydrocarbon products, such as C5-C100 hydrocarbon products. Processes include converting hydrocarbons (such as heavy naphtha, including paraffins and/or naphthene-rich heavy virgin naphtha, such as C3-C50 cyclic and/or C2-C50 acyclic alkanes (e.g., linear and or branched acyclic alkanes) to light distillates. In at least one embodiment, processes include a dehydrogenation stage, a cross-metathesis stage, and a hydrogenation stage to produce polyolefin products.

[0020] Catalyst systems used for processes of the present disclosure include one or more alkane dehydrogenation catalyst, ring-opening metathesis catalyst, and/or polymerization catalyst, olefin hydrogenation catalyst, and an optional support. In one aspect, a light distillate product includes the one or more C5-C200 hydrocarbon product(s), such as the one or more C5-C100 hydrocarbon product(s). The light distillate product may be blended with one or more other components (e.g., additives) to produce, for example, a fuel composition (e.g., higher value diesel (cetane)), waxes, lubricant range products, and base stocks.

[0021] The present disclosure provides processes including catalytic dehydrogenation - cross metathesis - hydrogenation by: i) dehydrogenating C3-C50 cyclic alkanes and C2-C50 acyclic alkanes in a heavy naphtha range (e.g., coker naphtha; catalytic naphtha), including paraffins and naphthenes, to form C2-C50 acyclic olefm(s) and C3-C50 cyclic olefm(s); ii) treating the acyclic olefm(s) and the cyclic olefm(s) under conditions (e.g., ring-opening cross-metathesis, such as Ring Opening Metathesis Polymerization,“ROMP”) to form C5-C200 olefins, such as C5-C 100 olefins, thus forming higher molecular weight compounds in the distillate range (or greater); iii) hydrogenating the C5-C200 olefins (such as C5-C200 polyolefin products), such as the C5-C 100 olefins (such as C5-C 100 polyolefin products, such as C5-C100 diolefin products ), to form saturated products in the distillate range (or greater).

[0022] Processes of the present disclosure may be substantially thermo-neutral, meaning that the enthalpies of the products and reactants are similar, such that the reaction is not significantly endothermic, which would require higher temperatures. Thermo-neutral processes of the present disclosure can enable low temperature molecular weight growth of alkanes with low/reduced energy intensity (or greenhouse gas emission). Processes of the present disclosure may provide: i) little to no introduction of additional branches to the product(s) other than those carried from the feed; ii) little to no formation of light products if the feed composition is properly controlled; and/or iii) a wide range of operating temperatures (e.g., from about 0°C to about 400°C) for the ring-opening cross-metathesis process, allowing tailoring or reaction conditions (depending on feed and catalyst) to match the conditions for other further reactions (e.g., hydroisomerization, cyclization, aromatization, Diels- Alder, and/or alkylation).

[0023] For the purposes of the present disclosure, the numbering scheme for the Periodic Table Groups is used as described in CHEMICAL AND ENGINEERING NEWS, 63(5), pg. 27 (1985). Therefore, a“group 4 metal” is an element from group 4 of the Periodic Table, e.g., Hf, Ti, or Zr.

[0043] The term“tandem reaction”, also referred to as“cascade reaction”, or“domino reaction”, refers to a chemical process including at least two or more consecutive reactions such that each subsequent reaction occurs by means of the chemical functionality formed in the previous reaction. The isolation of the intermediates formed during a tandem reaction may not be required. The reaction conditions of a tandem reaction might not change among the consecutive processes of a cascade and new reagents might not be added after the initial process. A“one-pot” sequence consisting of a single catalytic transformation and a subsequent stoichiometric modification does not constitute a tandem catalysis, even though the substrate has undergone two distinct transformations.

[0044] The term“olefin” refers to an unsaturated hydrocarbon compound having a hydrocarbon chain containing at least one carbon-to-carbon double bond in the structure thereof, wherein the carbon-to-carbon double bond does not constitute a part of an aromatic ring.

wherein each instance of R is independently a hydrocarbyl group, such as saturated hydrocarbyl group.

[0049] The term“internal olefin” includes olefins that are vinylenes.

[0050] The term“tri- substituted vinylene” means an olefin having the following formula:

[0051] The term“tetra- substituted vinylene” means an olefin having the following formula: wherein each instance of R is independently a hydrocarbyl group, such as a saturated hydrocarbyl group.

[0052] An internal olefin (e.g., monomers) of the present disclosure can be a linear or branched C4-C50 olefin having one or more carbon-carbon double bonds along the olefin backbone (also referred to as“internal unsaturation”) instead of, or in addition to, a carbon-carbon double bond at a terminus of the olefin (also referred to as“terminal unsaturation”). Linear or branched C4-C50 internal olefins may be referred to as C4-C50 internal-olefins. In addition to internal unsaturations, a C4-C50 internal olefin may additionally have one or more terminal unsaturations. An internal olefin can have one or more cis-conformations or one or more trans-conformations.

In at least one embodiment, an internal olefin is selected from a cis-configuration, trans-configuration, or mixture thereof of one or more of 2-butene, 2-pentene, 2-hexene, 3 -hexene, 2-heptene, 3-heptene, 2-octene, 3-octene, 4-octene, 2-nonene, 3-nonene, 4-nonene, 2-decene, 3-decene, 4-decene, and 5- decene. Internal olefins of the present disclosure can be obtained from commercial sources (such as Sigma Aldrich or TCI) and/or may be obtained from refined hydrocarbon feeds such as fluid catalytic cracking (FCC) gasoline or coker naphtha.

Dehydrogenation Processes

[0053] The present disclosure provides processes for converting a hydrocarbon feedstock (e.g., heavy naphtha; biomass) comprising contacting the feedstock with a first catalyst, such as a dehydrogenation catalyst. The hydrocarbon feedstock to be dehydrogenated may include, in whole or in part, a liquefied petroleum gas (LPG), a naphtha stream, having a boiling point in the range of about 70°C to about 185°C, a gas oil (e.g., light, medium, or heavy gas oil) having an initial boiling point above 200°C, a 50% point of at least 260°C and an end point of at least 350°C. The feedstock may also include vacuum gas oils, thermal oils, residual oils, cycle stocks, whole top crudes, tar sand oils, shale oils, synthetic fuels, heavy hydrocarbon fractions derived from the destructive hydrogenation of coal, tar, pitches, asphalts, hydrotreated feedstocks derived from any of the foregoing.

[0054] Heavy naphtha includes both paraffins and naphthenes (e.g., derived from coal, shale, or petroleum). For example, a naphtha may include from about 15 wt% to about 30 wt% paraffins, from about 5 wt% to about 20 wt% cyclo-paraffins, from about 10 wt% to about 30 wt% olefins, from about 1 wt% to about 10 wt% cycloolefins, and from about 10 wt% to about 40 wt% aromatics. Heavy naphtha can be converted to olefins, such as mono-olefins, using dehydrogenation. The heavy naphtha feed can be processed“as-is”, or optionally separated into paraffin and naphthene fractions, or further fractionated to individual carbon number. The naphtha feed may include one or more of n-hexane, n- heptane, cyclohexane, methylcyclohexane, methylcyclopentane, benzene, toluene, xylenes, or a mixture thereof. Dehydrogenation processes of the present disclosure include the dehydrogenation of C2-C50 acyclic alkanes and C3-C50 cyclic alkanes in a heavy naphtha range (e.g., coker naphtha; catalytic naphtha), including paraffins and/or naphthenes, to form C2-C50 acyclic olefins and C3-C50 cyclic olefins.

[0055] Furthermore, the feed composition can be controlled by introducing, injecting, feeding, co feeding, a defined amount of a defined hydrocarbon starting materials, thus by controlling the ratio of the starting material. Accordingly, the average molecular weight of the products can be controlled subsequently. For instance, longer molecular weight range products can be produced when less acyclic starting material (e.g., linear acyclic paraffins) is introduced to the feed. For example, when the hydrocarbon starting material is one or more Cn cyclic alkane(s), with n being the number of carbons of the alkane, and x being the number of cyclic alkane used for the reaction, the average molecular weight of the product can be defined as [xCn + carbon number of the acyclic alkane feed], with x > 2, and/or 3 < n < 100). For example, an average molecular weight of the product formed via combination of three cyclopentane molecules and one propane molecule can be [3Cs + C3 = C 1 x] .

[0056] Alternatively, shorter molecular weight range products (e.g., shorter range diesel) can be produced when more linear acyclic starting material is added to the feed. For example, linear acyclic starting material, such as linear acyclic paraffins, can be combined with one or more cyclic and/or acyclic alkane(s) either before, or after, alternatively before and after, the introduction of one or more cyclic and acyclic alkane(s) into the reactor.

[0057] A dehydrogenation process can involve contacting a C3-C50 cyclic alkane and a C2-C50 acyclic alkane feed with a catalyst system including platinum group metals, alloys, oxides, carbides, nitrides, and/or sulfides of individual transition metal and/or a mixed metal catalyst. The catalyst system can be bulk and/or supported. Suitable supports are non-acidic oxides including silica, aluminas, zirconia, titania, ceria, non-acidic clays, or basic oxides (such as magnesia, hydrotalcites, or lanthanum oxide). The catalyst system may include a transition metal oxide, such as CuO, Ag20, ZnO, NiO, CoOx, FeOx, MnOx, CrOx, or VOx, for example, or mixtures thereof, where x can be 1 to 3.5. In at least one embodiment, the dehydrogenation process is mediated by copper oxide (CuO). C2-C5 ₀ acyclic olefins and C3-C5 ₀ cyclic olefins products can be substituted and/or non-sub stituted olefins products.

[0058] In a dehydrogenation process, a feed stream including at least 2 wt% of C2 to C50 cyclic alkanes and C2 to C50 acyclic alkanes can be contacted with a catalyst suitable for a dehydrogenation process, with or without the presence of a solvent, such as the hydrocarbons including C3 to C50 cyclic alkanes and C2 to C50 acyclic alkanes of the feed stream can be used directly as solvent.

[0059] Optionally one or more solvent(s) can be used for the process of the present disclosure. The solvent may be a saturated hydrocarbon or an aromatic solvent such as n-hexane, n-heptane, cyclohexane, benzene, toluene, xylenes, or a mixture thereof. Contacting the catalyst with a feedstream comprising the C2 to C50 alkanes may be carried out in an atmosphere inert under the process conditions, such as in nitrogen, argon, or a mixture thereof. Naphtha, including both paraffins and naphthenes, may include various ranges of cyclic and acyclic alkanes. Hence, controlling a co feed molar ratio of cyclic alkanes to acyclic alkanes starting materials provides control of the molecular weight of the C5-C200 olefin products, such as the C5-C100 olefin products. For example, C3-C50 cyclic alkanes can be cyclopropane, cyclobutane, cyclopentane, cyclohexane, cycloheptane, cyclooctane. Examples of C2-C50 acyclic alkanes can be ethane, propane, butane, pentane, hexane, heptane, octane.

[0060] A molar ratio of one or more cyclic alkanes to acyclic alkanes can be from about 1 : 1000 to about 1000: 1, such as from about 1 :700 to about 700: 1, such as from about 1 :500 to about 500:1, such as from about 1 :250 to about 250: 1, such as from about 1 : 100 to about 100: 1, such as from about 1 :50 to about 50: 1, such as from about 1 : 10 to about 10:1.

[0061] In at least one embodiment, a dehydrogenation process is performed at a temperature of 450°C or less, such as from about 100°C to about 450°C, such as from about 150°C to about 350°C (e.g., 275°C). A dehydrogenation process of the present disclosure may be carried out by mixing a solution of C3-C50 cyclic alkanes and C2-C50 acyclic alkanes and the catalyst(s), cooling the solution, and optionally allowing the mixture to increase in temperature. A dehydrogenation process can be performed at a pressure greater than 1 bar gauge, such as from about 1 bar gauge to about 2,000 bar gauge, such as about 1 bar gauge to about 1,000 bar gauge, such as about 1 bar gauge to about 750 bar gauge, and/or for a period of time of from about 5 minutes to about 20 hours, such as from about 30 minutes to about 4 hours, such as from about 1 hour to about 3 hours. In at least one embodiment, dehydrogenation is performed at a temperature higher than 400°C; and/or at a pressure of from about less than 1 bar gauge to about 2 bar gauge.

[0062] In at least one embodiment, the process for the production of a C2-C50 acyclic olefin of Formula (I) and a C3-C50 cyclic olefin of Formula (II) includes: dehydrogenating at least one C2-C50 acyclic alkane and at least one C3-C50 cyclic alkane by contacting the at least one C2-C50 acyclic alkane and the at least one C3-C50 cyclic alkane with a catalyst system in at least one solution dehydrogenation reactor at a reactor pressure of from 1 bar gauge to 2000 bar gauge and a reactor temperature of from about 100°C to about 450°C. The C2-C50 acyclic olefins (I) and C3-C50 cyclic olefins (II) products can be recovered and analyzed by GC.

Dehydrogenation Catalysts

[0063] Dehydrogenation catalyst(s) of the present disclosure may include platinum group metals (e.g., Pd, Rh, Pt), alloys (e.g., bimetallic Pt-Fe catalysts, Cu-Al alloy catalyst, Pt-Zn alloy nanocluster catalyst), oxides, carbides (e.g., bulk W-Mo mixed carbides, Mo carbide modified nanocarbon catalysts), nitrides (e.g., B-N catalyst), and/or sulfides (e.g., Mo-sulfide-alumina catalyst) of individual transition metal and/or mixed metal catalyst.

Optional Support Materials for Dehydrogenation Catalysts Metathesis Catalysts and/or

Hydrogenation Catalysts

[0065] In embodiments herein, the catalyst system may include an inert support material. The supported material can be a porous support material, for example, talc, and inorganic oxides. Suitable supports are non-acidic oxides including silica, theta-alumina or any suitable aluminas, zirconia, titania, ceria, non-acidic clays, or basic oxides (such as magnesia, hydrotalcites, or lanthanum oxide). Other support materials may include zeolites, organoclays, or another organic or inorganic support material, or mixtures thereof.

[0066] The support material can be an inorganic oxide in a finely divided form. Suitable inorganic oxide materials for use in catalyst systems herein include groups 2, 4, 10, 11, 12, 13, and 14 metal oxides, such as silica, alumina, MgO, T1O2, ZrCh, rare-earth oxides (e.g., La2Cb, Ce02), and mixtures thereof. Other inorganic oxides that may be employed either alone or in combination with the silica, or alumina, are magnesia, titania, zirconia. Suitable supports may include magnesia, titania, zirconia, montmorillonite, phyllosilicate, zeolites, talc, clays. Also, combinations of these support materials may be used, for example, silica-chromium, silica-alumina, silica-titania. Support materials include AI2O3, Zr02, S1O2, and combinations thereof, such as S1O2, AI2O3, or S1O2/ AI2O3.

[0067] The support material should be dry, that is, free of absorbed water. Drying of the support material can be effected by heating or calcining at about 100°C to about 1000°C, such as at least about 400°C. When the support material is silica, it is heated to at least 110°C, such as from about 110°C to about 850°C, such as at about 600°C, for example; and/or for a time of about 1 minute to about 100 hours, from about 12 hours to about 72 hours, or from about 24 hours to about 60 hours. The calcined support material must have at least some reactive hydroxyl (OH) groups to produce supported catalyst systems of the present disclosure. The calcined support material is then contacted with at least one dehydrogenation/ring-opening metathesis/hydrogenation catalyst system comprising at least one dehydrogenation catalyst compound, at least one ring-opening metathesis catalyst compound, and/or at least one hydrogenation catalyst compound.

[0068] The support material, having reactive surface groups, such as hydroxyl groups, can be slurried in a non-polar solvent and the resulting slurry can be contacted with a solution of a catalyst compound(s). In at least one embodiment, the slurry of the support material is first contacted with a first catalyst compound, such as a dehydrogenation catalyst compound for a period of time in the range of from about 0.5 hours to about 24 hours, from about 2 hours to about 16 hours, or from about 4 hours to about 8 hours. Then, a solution of a second catalyst compound, such as a ring-opening metathesis catalyst compound, can be contacted with the isolated support/first catalyst compound. In at least one embodiment, the supported catalyst system is generated in situ. In alternate embodiment, the slurry of the support material is first contacted with the first catalyst compound for a period of time in the range of from about 0.5 hours to about 24 hours, from about 2 hours to about 16 hours, or from about 4 hours to about 8 hours. The slurry of the supported catalyst compound is then contacted with the second catalyst compound solution. Then a third catalyst compound (e.g., hydrogenation catalyst) can be added, as a solution or neat, to the solution mixture including the first and the second catalysts.

[0069] The mixture of the catalyst compounds and support can be heated to about 0°C to about 70°C, such as about 23°C to about 60°C, such as at room temperature. Contact times may range from about 0.5 hours to about 24 hours, from about 2 hours to about 16 hours, or from about 4 hours to about 8 hours.

[0085] For example, the cyclic olefin monomer represented by formulae (II), (IV), and (V) can be a vinylenes, such as an olefin with a“cis-“ conformation, such as an olefin with“trans-“ conformation, or a mixture thereof, thus at any proportion thereof. Furthermore, the cyclic olefin monomer can be a tri-substituted vinylene. Traces of tetra- substituted vinylene may be present in the reaction mixture.

[0086] The C2-C50 acyclic olefins of Formula (I) (such as C2-C20 acyclic olefins, such as C9-C11 acyclic olefins) can be produced with a weight average molecular weight (M _w ) of from about 28 g/mol to about 700 g/mol, such as from about 28 g/mol to about 420 g/mol, such as from about 28 g/mol to about 280 g/mol. The C3-C50 cyclic olefins of Formula (II) can be produced with a weight average molecular weight (M _w ) of from about 40 g/mol to about 698 g/mol, such as from about 40 g/mol to about 418 g/mol, such as from about 40 g/mol to about 278 g/mol.

Polymerizing the Olefin Products

[0087] The olefin products of Formula (I) and Formula (II) are polymerized (e.g., copolymerized) to form products. For example, olefin metathesis allows the substituents of different olefins to rearrange into new olefins, and therefore form new products. When two acyclic olefins undergo an olefin metathesis insertion reaction, two new olefins are formed; therefore the molecular weight growth is limited. However, the present disclosure provides a process such that a cyclic olefin and an acyclic olefin can be polymerized together (e.g., copolymerized), which gives one product having the sum of carbon numbers of the feed molecules. For example, ring opening metathesis of the cyclic olefins can lead to polymers (e.g., Ring Opening Metathesis Polymerization, ROMP), such that larger molecular weight molecules can also be formed. The olefins feed may include: i) strained cyclic olefins (e.g., cyclopentene, norbornene); ii) a mixture of two or more feeds, for example, a reaction between a mixture of Cs olefins (e.g., pentenes including cyclopentene) may result in the formation of Cio and Cis products, thus due to the cyclopentene polymerization. Accordingly, the average molecular weight of the olefin products can be controlled by adjusting: i) the cyclic/acyclic olefin ratio; ii) the catalyst formulation; and/or iii) having secondary reactions to further break up larger molecules (e.g., ethenolysis reactions - using cross metathesis with ethylene to break up larger olefin molecules), and unreactive cyclic olefins (e.g., cyclohexene) can be used to form oligomers.

[0088] For example, ethenolysis is a catalytic process, such as a cross metathesis, that can convert higher molecular weight internal alkenes to more valuable terminal alkenes (e.g., alpha-olefins) by degrading such internal olefins using ethylene as a reagent. For example, the ethenolysis can be employed to produce diolefins, e.g., a, co-dienes, by reacting a cyclic alkene with ethylene, in presence of a transition metal catalyst suitable for cross metathesis (e.g., Rhenium(VII) oxide supported on alumina). Furthermore, the resulting terminal alkenes (e.g., alpha-olefins) can be subject to an oligomerization process in the presence of a Lewis acid catalyst, such as BF3, thus producing polyalphaolefms (PAOs) base stocks, such as Group IV base stocks. In this regard, a recycle process involving a dehydrogenation process performed on a polymer, such as polyethylene, followed by an olefin metathesis process, can lead to fragmentation of the polymer. Also, the conversion to terminal alkenes (e.g., alpha-olefins) can yield the formation of vinyl terminated monomers, which can be used for mold-making elastomers or encapsulants/sealants for electronic components, for instance.

[0089] The present disclosure provides a method for synthesizing an olefmic polymer, such as C5- C200 olefins (III), such as C5-C100 olefins (III), using a ROMP reaction, comprising contacting an olefin monomer with a catalytically effective amount of an olefin metathesis catalyst under reaction conditions effective to allow the ROMP reaction to occur, wherein the olefin monomer contains a plurality of heteroatoms, at least two of which are directly or indirectly linked to each other. By “directly” linked is meant that the two heteroatoms are linked to each other through a direct, covalent bond. By“indirectly” linked is meant that one or more atoms are present between the heteroatoms. For example, the“indirect” linkage herein refers to the presence of a single atom (that may or may not be substituted) to which each heteroatom can be linked through a direct covalent bond. In at least one embodiment, the olefin monomer contains one double bond, and the two heteroatoms are symmetrically positioned with respect to any axis that is perpendicular to the double bond.

[0090] In at least one embodiment, a C5-C200 olefin, such as a C5-C100 olefin is represented by formula (III):

[0091] In at least one embodiment, R ⁵ , R ⁶ , R ⁹ , and R ¹⁰ are independently selected from hydrogen, hydrocarbyl (e.g., C1-C20 alkyl, C5-C20 aryl, C5-C30 aralkyl, or C5-C30 alkaryl), substituted hydrocarbyl (e.g., substituted C1-C20 alkyl, Cs-C2o aryl, C5-C30 aralkyl, or C5-C30 alkaryl), heteroatom-containing hydrocarbyl (e.g., C 1-C20 heteroalkyl, C5-C2oheteroaryl, heteroatom-containing C5-C30 aralkyl, or heteroatom-containing C5-C30 alkaryl), substituted heteroatom-containing hydrocarbyl (e.g., substituted C1-C20 heteroalkyl, C5-C20 heteroaryl, heteroatom-containing C5-C30 aralkyl, or heteroatom-containing C5-C30 alkaryl).

The cyclic groups may be aliphatic or aromatic, and may be heteroatom-containing and/or substituted.

[0092] One group of such cyclic olefins are those of formula (II) wherein R ⁶ and R ¹⁰ are hydrogen, R ⁵ is -(Q)k-E wherein k is zero and -E is— Y— (R ¹⁶ )n, and R ⁹ is -(Q)k-E wherein k is zero and E is— Z— (R ¹⁷ )j, with Y and Z are independently N, O, or S, k is zero or 1, j and n are independently zero or 1, Q is a one-atom to five-atom linkage. In at least one embodiment, and when the monomer is bicyclic (e.g., when R ¹⁶ and R ¹⁷ are linked), then Q is a one-atom or two-atom linkage, such as a linkage that has one or two optionally substituted atoms between the two carbon atoms to which Q is bound. For example, Q can be of the formula— CR ^{1 1} R ¹² — (Q ^x )q’— wherein q’ is zero or 1, Q ¹ is CR ¹³ R ¹⁴ , O, S, or NR ^15’ , and R ¹¹ , R ¹² , R ¹³ , R ^14’ , and R ¹⁵ are independently selected from hydrogen, hydrocarbyl (e.g., C1-C2 ₀ alkyl, C2-C2 ₀ alkenyl, C2-C2 ₀ alkynyl, Cs-C2o aiyl, C ₆ -C24 alkaryl, C ₆ -C24 aralkyl, Ci- C2 ₀ alkyl, Cs-C2o aiyl, C5-C3 ₀ aralkyl, or C5-C3 ₀ alkaryl), substituted hydrocarbyl (e.g., substituted Ci- C2 ₀ alkyl, C2-C2 ₀ alkenyl, C2-C2 ₀ alkynyl, C5-C2 ₀ aryl, C ₆ -C24 alkaryl, C ₆ -C24 aralkyl, C1-C2 ₀ alkyl, C5- C2o aryl, C5-C ₃₀ aralkyl, or C5-C ₃₀ alkaryl), heteroatom-containing hydrocarbyl (e.g., Ci- C2 ₀ heteroalkyl, C5-C2 ₀ heteroaryl, heteroatom-containing C5-C ₃₀ aralkyl, or heteroatom-containing C5-C ₃₀ alkaryl), substituted heteroatom-containing hydrocarbyl (e.g., substituted C1-C2 ₀ heteroalkyl, C5-C2 ₀ heteroaryl, heteroatom-containing C5-C ₃₀ aralkyl, or heteroatom-containing C5-C ₃₀ alkaryl); When q’ is 1, suitable examples of linkages can be wherein Q ¹ is CR ¹³ R ¹⁴ , thus providing a substituted or unsubstituted ethylene moiety to the cyclic olefin of Formula (IV). Accordingly, when R ¹¹ , R ¹² , R ¹³ , and R ¹⁴ are hydrogen, then Q is ethylene. When q’ is zero, the linkage can be substituted or unsubstituted methylene, and a suitable linkage within this group can be methylene (e.g., when R ^{1 1} and R ¹² are both hydrogen; and R ¹⁶ and R ¹⁷ are independently selected from hydrogen, hydrocarbyl, substituted hydrocarbyl, heteroatom-containing hydrocarbyl, substituted heteroatom- containing hydrocarbyl, and amino groups, wherein R ¹⁶ and R ¹⁷ may be taken together to form a cyclic group, and further wherein Y and Z are directly or indirectly linked. In at least one embodiment, the cyclic olefin monomer is represented by formula (IV):

In at least one embodiment, and when the monomer is bicyclic (e.g., when R ⁵ and R ¹⁰ are linked), then X is a one-atom or two-atom linkage, such as a linkage that has one or two optionally substituted atoms between the two carbon atoms to which Xis bound. For example, X can be of the formula— CR ^U R ¹² — (X ⁴ ) _q— wherein q is zero or 1, X ¹ is CR ¹³ R ¹⁴ , O, S, or NR ¹⁵ , and R ¹¹ , R ¹² , R ¹³ , R ¹⁴ , and R ¹⁵ are independently selected from hydrogen, hydrocarbyl (e.g., Ci- C20 alkyl, C2-C20 alkenyl, C2-C20 alkynyl, C5-C20 aryl, C6-C24 alkaryl, C6-C24 aralkyl, C1-C20 alkyl, C5- C2o aryl, C5-C30 aralkyl, or C5-C30 alkaryl), substituted hydrocarbyl (e.g., substituted C 1-C20 alkyl, C2- C20 alkenyl, C2-C20 alkynyl, Cs-C2o aryl, C6-C24 alkaryl, C6-C24 aralkyl, C1-C20 alkyl, Cs-C2o aryl, C5- C30 aralkyl, or C5-C30 alkaryl), heteroatom-containing hydrocarbyl (e.g., C1-C20 heteroalkyl, C5- C20 heteroaryl, heteroatom-containing C5-C30 aralkyl, or heteroatom-containing C5-C30 alkaryl), substituted heteroatom-containing hydrocarbyl (e.g., substituted C 1-C20 heteroalkyl, C5-C20 heteroaryl, heteroatom-containing C5-C30 aralkyl, or heteroatom-containing C5-C30 alkaryl).

When q is 1, suitable examples of linkages can be wherein X ¹ is CR ¹³ R ¹⁴ , thus providing a substituted or unsubstituted ethylene moiety.

[0093] In at least one embodiment, forming the products from the cyclic olefin(s) and acyclic olefin(s), e.g., by ring-opening cross-metathesis, such as ROMP, is performed at a cyclic/acyclic olefin molar ratio of from about 1 : 1000 to about 1000: 1, such as from about 1 :700 to about 700: 1, such as from about 1 :500 to about 500: 1, such as from about 1 :250 to about 250: 1, such as from about 1 : 100 to about 100: 1, such as from about 1 :50 to about 50: 1, such as from about 1 : 10 to about 10: 1; and/or using, for example, a group 6, 7, or 8 transition metal catalyst complex (e.g., Re, Ru, Os, Mo, W), and/or any suitable heterogeneous metathesis catalysts including Re, Mo, or W oxides (further details on the catalyst will be described in the next section).

[0094] Any solvent suitable for metathesis reactions may be utilized in the present disclosure. Suitable conditions for performing provided processes may use one or more solvents. For example, the ring-opening cross-metathesis may occur in one or more organic solvents. Examples of such organic solvents include, but are not limited to, hydrocarbons such as benzene, toluene, and pentane, halogenated hydrocarbons such as dichloromethane, or polar aprotic solvents, such as ethereal solvents including ether, DME, tetrahydrofuran (THF), or dioxanes, or protic solvents, such as alcohols, or mixtures thereof. In at least one embodiment, one or more solvents are deuterated. Furthermore, examples of solvents that may be used in the ring-opening cross-metathesis reaction may include organic, polar aprotic, protic, or aqueous solvents that are inert under the ring-opening cross metathesis conditions, such as aromatic hydrocarbons, chlorinated hydrocarbons, ethers, aliphatic hydrocarbons, alcohols, water, or mixtures thereof. Suitable organic solvents for ring-opening cross metathesis can be, but are not limited to, dichloromethane, dichloroethane, toluene, benzene, acetonitrile, p-xylene, methylene chloride, 1,2-dichloroethane, di chlorobenzene, chlorobenzene, tetrahydrofuran, diethylether, pentane, methanol, ethanol, water, or mixtures thereof, such as the solvent can be benzene, toluene, xylenes, methylene chloride, 1,2-dichloroethane, di chlorobenzene, chlorobenzene, tetrahydrofuran, diethylether, pentane, methanol, or ethanol. In at least one embodiment, the solvent is toluene or 1,2-dichloroethane. The solubility of the C5-C200 olefins, such as the C5-C100 olefins (III) formed in the ring-opening cross-metathesis reaction will depend on the choice of solvent and the molecular weight of the C5-C200 olefins, such as the C5-C 100 olefins (III) obtained. Under certain circumstances, no solvent is needed. The feedstock itself can be used directly as solvent. In at least one embodiment, a single solvent is used. Alternatively, mixtures of two or more solvents are used. For example, when a solvent mixture is used, the solvent mixture can be a mixture of an ethereal solvent and a hydrocarbon. Examples of such mixtures may include, for instance, an ether/benzene mixture, or a DME/Toluene mixture. In at least one embodiment, an exemplary mixture is a DME/Toluene mixture at a DME/Toluene ratio of about 1 : 1. Solvent mixtures may be comprised of equal volumes of each solvent or may contain one solvent in excess of the other solvent or solvents. In at least one embodiment wherein a solvent mixture is comprised of two solvents, the solvents may be present in a ratio of about 20: 1, such as about 10: 1, such as about 9:1, such as about 8: 1, such as about 7: 1, such as about 6: 1, such as about 5: 1, such as about 4: 1, such as about 3: 1, such as about 2: 1, such as about 1 : 1. A solvent mixture may include an ethereal solvent and a hydrocarbon, such as the solvents may be present in a ratio of about 20: 1, such as about 10: 1, such as about 9: 1, such as about 8: 1, such as about 7: 1, such as about 6: 1, such as about 5: 1, such as about 4: 1, such as about 3: 1, such as about 2: 1, such as about 1 : 1 ethereal solventhydrocarbon. Furthermore, a solvent mixture may include a mixture of ether and benzene in a ratio of about 5: 1.

[0095] A wide range of operating temperatures (e.g., from about ambient temperature to about 400°C) for the cross-metathesis process can be tailored, thus depending on feed and catalyst, in order to match the conditions for other reaction processes. In at least one embodiment, the ring-opening cross-metathesis process is carried out at a temperature of from about 0°C to about 450°C, such as from about 25°C to about 350°C, such as from about 50°C to about 250°C, alternatively from about 0°C to about 100°C, such as from about 25°C to about 75°C. Furthermore, a ring-opening cross metathesis may be carried out at reflux.

[0096] Synthesizing an olefmic polymer, such as C5-C200 olefins (III), such as C5-C100 olefins (III), using a ROMP reaction, can be performed at a pressure of from about 0.1 kPa to about 2,000 kPa, such as from about 100 kPa to about 2,000 kPa. In at least one embodiment, the ring-opening cross-metathesis process is carried out at ambient pressure. In an alternate embodiment, the ring opening cross-metathesis process is carried out at reduced pressure. For example, the ring-opening cross-metathesis process can be performed at an absolute pressure of from about 0.1 kPa to about 5 kPa, such as from about 0.5 kPa to about 4 kPa, such as from about 1 kPa to about 3kPa. Suitable conditions may involve a reaction time of from about 5 minutes to about 120 hours, such as from about 10 minutes to about 96 hours, such as from about 20 minutes to about 48 hours, such as from about 30 minutes to about 24 hours.

[0097] Additional coupling may occur during the ring-opening cross-metathesis of C2-C50 acyclic olefins of Formula (I) and C3-C50 cyclic olefins of Formula (II) such as a homocoupling reaction between two or more C2-C50 acyclic olefins of Formula (I) or a homocoupling reaction between two or more C3-C50 cyclic olefins of Formula (II) (e.g., cyclopentene), and the coupling reaction can be controlled via the cyclic/acyclic olefin molar ratio, for example. Interestingly, the acyclic olefins can act as chain transfer agents to regulate the molecular weight of polymers produced.

Ring-Opening Cross-Metathesis Catalysts

[0098] In at least one embodiment, the ring-opening cross-metathesis, such as ROMP, is performed using a transition metal catalyst complex, such as a group 6, 7, or 8 transition metal catalyst complex (e.g., Re, Ru, Os, Mo, W), and/or any suitable heterogeneous metathesis catalysts including Re, Mo, or W oxides, for example.

[0099] In at least one embodiment, the ring-opening cross-metathesis, such as ROMP, is performed using a soluble group 6, 7 or 8 transition metal catalyst complex. The ring-opening cross metathesis catalyst can be used at a catalyst loading of from about 0.001 mol% to about 10 mol%, such as from about 0.001 mol% to about 5 mol%, such as from about 0.001 mol% to about 1 mol%. High molecular weight olefins (e.g., > 300,000 g/mol) can be achieved with a molar ratio of feed to catalyst of 500: 1 or greater, such as 600: 1 or greater, such as 700: 1 or greater.

[0100] The ROMP reaction can be carried out in an inert atmosphere by dissolving a catalytically effective amount of an olefin metathesis catalyst, such as a group 8 transition metal complex of Formula (A), in a solvent, and adding the C3-C50 cyclic olefin monomer (such as a monomer of Formula (II)), optionally dissolved in a solvent, to the catalyst solution. In at least one embodiment, the reaction is agitated (e.g., stirred). The progress of the reaction can be monitored by standard techniques, e.g., nuclear magnetic resonance spectroscopy and/or GC analysis. For example, metathesis catalysts used for purposes of the present disclosure can be any suitable metathesis catalyst, such as a Grubbs-type catalyst or Schrock-type catalyst, such as a second generation Grubbs catalyst including Ru (Scheme 1, structure A), or Schrock-type catalyst including Mo (Scheme 1, structure B), or heterogeneous catalysts including Re, Mo, or W oxides to allow for facile use of flow reactors. Examples of suitable metathesis catalysts are described in U.S. 6,803,429 B2; Grubbs, R.,“Handbook of Metathesis”, vol. 3, 2003, Wiley-VCH, Weinheim; Schrock et al.

[0101] Alternatively, the ROMP reaction can be carried out in an inert atmosphere by dissolving a catalytically effective amount of an olefin metathesis catalyst, such as a group 8 transition metal complex of Formula (B)) in a solvent, and adding the C3-C50 cyclic olefin monomer (such as a monomer of Formula (II)), optionally dissolved in a solvent, to the catalyst solution. In at least one embodiment, the reaction is agitated (e.g., stirred). The progress of the reaction can be monitored by standard techniques, e.g., nuclear magnetic resonance spectroscopy and/or GC analysis.

[0102] In another embodiment, the ring-opening cross-metathesis, such as ROMP, is performed using a heterogeneous catalyst such as Re, Mo, or W oxide. Examples of suitable conditions for ring- opening cross-metathesis can be used as disclosed in Lwin, S.; Wachs, I. E.“Olefin Metathesis by Supported Metal Oxide Catalysts”, ACS Catal.( 2014), 4, 2505-2520, which is incorporated herein by reference

[0103] The resulting C5-C200 olefins, such as the C5-C100 olefins of Formula (III) can be obtained having a weight average molecular weight (M _w ) of from about 100 g/moT ¹ to about 2800 g/moT ¹ , such as from about 100 g/moT ¹ to about 1400 g/moT ¹ , such as from about 100 g/moT ¹ to about 500 g/moT ^l . For example, the C5-C200 olefins, such as the C5-C100 olefins of Formula (III) can be branched or linear polymers.

[0104] The C5-C200 olefins, such as the C5-C100 olefins (III) can be functionalized/substituted on one or more C=C bond(s) to form functionalized/substituted products containing a functional group (e.g., hydroxyl, mercapto, halogen (Cl, Br, or I), carboxylic, boryl, phosphoryl, sulfonato, nitrosyl), separated by a desired number of carbons. Examples of substitution/functionalization routes may include hydroisomerization, cyclization, aromatization, Diels-Alder [4+2] cycloaddition, alkylation, and/or hydrogenation to form functionalized C5-C200 products, such as functionalized C5-C100 products.

[0105] Furthermore, C5-C200 olefins (such as C5-C200 polyolefin products), such as C5-C 100 olefins (such as C5-C 100 polyolefin products) including substituted and/or non-sub stituted olefins, can be readily synthesized using C3-C50 cyclic olefins of Formula (IV).

In at least one embodiment, and when the monomer is bicyclic (e.g., when R ¹⁶ and R ¹⁷ are linked), then Q is a one-atom or two-atom linkage, such as a linkage that has one or two optionally substituted atoms between the two carbon atoms to which Q is bound. For example, Q can be of the formula— CR ¹¹ R ¹² — (Q ^x )q’— wherein q’ is zero or 1, Q ¹ is CR ¹³ R ¹⁴ , O, S, or NR ^15’ , and R ¹¹ , R ¹² , R ¹³ , R ^14’ , and R ¹⁵ are independently selected from hydrogen, hydrocarbyl (e.g., C 1-C20 alkyl, C2-C20 alkenyl, C2-C20 alkynyl, Cs-C2o aiyl, C6-C24 alkaryl, C6-C24 aralkyl, Ci- C20 alkyl, Cs-C2o aiyl, C5-C30 aralkyl, or C5-C30 alkaryl), substituted hydrocarbyl (e.g., substituted Ci- C20 alkyl, C2-C20 alkenyl, C2-C20 alkynyl, C5-C20 aryl, C6-C24 alkaryl, C6-C24 aralkyl, C1-C20 alkyl, C5- C2o aryl, C5-C30 aralkyl, or C5-C30 alkaryl), heteroatom-containing hydrocarbyl (e.g., Ci- C20 heteroalkyl, C5-C20 heteroaryl, heteroatom-containing C5-C30 aralkyl, or heteroatom-containing C5-C30 alkaryl), substituted heteroatom-containing hydrocarbyl (e.g., substituted C1-C20 heteroalkyl, C5-C20 heteroaryl, heteroatom-containing C5-C30 aralkyl, or heteroatom-containing C5-C30 alkaryl); When q’ is 1, suitable examples of linkages can be wherein Q ¹ is CR ¹³ R ¹⁴ , thus providing a substituted or unsubstituted ethylene moiety to the cyclic olefin of Formula (IV). Accordingly, when R ¹¹ , R ¹² , R ¹³ , and R ¹⁴ are hydrogen, then Q is ethylene. When q’ is zero, the linkage can be substituted or unsubstituted methylene, and a suitable linkage within this group can be methylene (e.g., when R ¹¹ and R ¹² are both hydrogen);

Hydrogenation Hydroisomerization and Production of Lubricants and Base Stocks

Base Stocks

[0112] In at least one embodiment, a base stock is a C5-C200 polyolefin product, such as a C5-C100 polyolefin product, such as a C25-C50 polyolefin product. A hydrocarbon product of the present disclosure, when added to a lubricating oil (as a viscosity modifier) or used as a lubricating oil, can reduce the tendency of the oil to change its viscosity with temperature in order to improve its viscosity index“VI”, and flow characteristics. Improving VI helps in maintaining constant the flow properties of the protective oil film. This means a high enough viscosity to avoid damage on engine parts when the temperature rises because of the engine heat and a low enough viscosity against the cold start and pumping. Hydrocarbon products of the present disclosure, such as the C6-C200 olefins, such as the C6- C100 olefins (III), (VI), and (VII), can have a VI of about 120 or greater, such as about 140 or greater, such as about 150 or greater, such as about 170 or greater, such as about 180 or greater, as determined according to ASTM D2270.

[0113] In addition, base stocks are affected by many properties including kinematic viscosity (KV), where an inverse relationship exists between KV and low-temperature fluidity, and VI, where a direct relationship exists between VI and low-temperature fluidity. Increasing the VI of a base stock by adding a polymer product of the present disclosure can provide improved viscometrics under both low-temperature and high-temperature regimes. VI itself represents the change in viscosity over a temperature range from 40°C to 100°C. The higher the VI, the lower the oil’s viscometric properties will change, and the flatter its profile will be over the temperature range. This can be extended to higher and lower temperatures. In at least one embodiment, a polyolefin product of the present disclosure, such as the C5-C100 olefins (III), (VI), and (VII), can have a kinematic viscosity at 100°C (KV100), as determined by ASTM D445, of about 20 cSt to about 200 cSt, such as from about 40 cSt to about 120 cSt, such as from about 50 cStto about 100 cSt. Additionally or alternatively, a polyolefin product of the present disclosure such as the C6-C100 olefins (III), (VI), and (VII), can have a kinematic viscosity at 40°C (KV40), as determined by ASTM D445, of about 150 cSt to about 2500 cSt, such as from about 150 cSt to about 1100 cSt.

[0114] In addition, glass transition temperature (Tg) is indicative of the fluidity of a material at low temperature operations. Tg can be measured using Differential Scanning Calorimetry (DSC) on a commercially available instrument (e.g., TA Instruments 2920 DSC). Tg is measured by equilibrating the sample at 100°C, isothermal for 5 minutes, ramping the temperature at 10°C/min to -100°C, isothermal for 5 minutes, ramping the temperature at 10°C/min to 100°C, and isothermal for 2 minutes. A polyolefin product of the present disclosure, such as the C6-C200 olefins, such as the C6- C100 olefins (III), (VI), and (VII), can have a glass transition temperature (Tg) of from about -110°C to about -50°C, such as from about -95°C to about -75°C, such as from about -95°C to about -85°C. Hydrogenation of Hydrocarbon Products

[0115] A polyolefin product, such as a C5-C100 olefin represented by (III), (VI), and (VII), can be catalytically hydrogenated to form a hydrogenated polyolefin product, such as a substituted or unsubstituted polymer product. A hydrogenated polyolefin product can be used as a lubricating oil base stock. The hydrogenation may be carried out in solution. The catalyst may be any suitable hydrogenation catalyst, such as a palladium catalyst supported on activated carbon or a Raney nickel catalyst. The hydrogenation can be carried out at elevated pressure, e.g., from 2,000 KPa to 10,000 KPa, such as from 4,500 KPa to 8,000 KPa. The hydrogenation reaction can be carried out at a temperature of from about 15°C to about 400°C, such as from 50°C to about 250°C, alternately from 30°C to about 70°C. The duration of the hydrogenation reaction may be from a few minutes to several days. After the hydrogenation reaction is complete, the reaction mixture can be cooled, depressurized and the solvent removed by vacuum distillation. The purity of the hydrogenated product can be determined by gas chromatography, and the viscosity of the resulting lubricant can be measured by rotary viscosimetry.

[0116] The hydrogenation process can be performed with any suitable late transition metals (group 6 to 12), alloys, carbides, or nitrides that can readily hydrogenate an olefin to a corresponding saturated product;

[0117] In at least one embodiment, a hydrogenation is performed using Ni/Kiselguhr as the catalyst, at a catalyst loading of from about lmol% to about 5 mol%; under a pressure of from about 200 psi (1,378.95 kPa) to about 400 psi (2757.9 kPa) of hydrogen; at a temperature of from about 15°C to about 300°C (e.g., 250°C); and/or a reaction time of from about 30 minutes to 4 hours.

[0118] In at least one embodiment, a hydrogenation is performed at an I/h/olefin molar ratio of from 1000: 1 to 100: 1; in the presence of from about 1000 mol% to about 1 mol% of H2; and/or a gas hourly velocity (GHSV) of from about 0.01 h ¹ to about 1000 h ¹ .

Hydrogenated Polyolefin Products

[0119] Hydrogenated polyolefin products, as base stocks, produced in accordance with processes of the present disclosure can possess high linearity which can provide improved flow, low temperature properties, and thickening efficiency. Alternatively, some hydrogenated polyolefin products can be used as diesel fuels having a high cetane number.

Hydrogenated Base Stocks

[0120] In at least one embodiment, a hydrogenated base stock is a C5-C200 hydrogenated polyolefin product, C5-C100 hydrogenated polyolefin product, such as a C5-C50 hydrogenated polyolefin product, such as a C25-C50 hydrogenated polyolefin product.

[0121] The high linearity of hydrogenated polyolefin products of the present disclosure can provide improved flow properties, as compared to highly branched polyolefin products. In addition, low amounts of methyl (-CH3) moieties are also indicative of high linearity of a hydrogenated polyolefin product.

[0122] However, branched polyolefin products can be used as lubricant range products, which are of high commercial interest. Branching of said polyolefin products can be controlled using processes of the present disclosure, for example by controlling the cyclic/acyclic olefin monomer ratio and/or by using an alkyl-substituted olefin monomer suitable for the formation of a branched polyolefin product, such as an alkyl-substituted cyclic olefin and/or an alkyl-substituted acyclic olefin, such as a mono- and/or poly-alkyl substituted olefin, with at least one or more heteroatom, or without any heteroatom.

Hydroisomerization

[0123] Hydroisomerization of the C5-C200 polymer products, such as the C5-C100 polymer products represented by Formula (VIII) or Formula (IX), such as long-chain paraffins, can be performed using one or more suitable hydroisomerization catalyst(s) (e.g., MSDW-3™ catalyst from ExxonMobil Chemical Company). Hydroisomerization of the C5-C100 polymers products of Formula (VIII) or Formula (IX) can reduce the content of linear paraffins in hydrocarbon mixtures by producing branched compounds, and can enable the production of high-octane gasoline and low-pour-point diesel. The hydroisomerization of the C5-C100 polymers products represented by formula (VIII) or Formula (IX) can improve the viscosity properties of waxy feedstocks, for example.

[0124] In at least one embodiment, the C6-C200 olefins, such as the C5-C100 olefins (III), (VI), and/or (VII), are hydrogenated to saturated products. Furthermore, the resulting saturated products formed after hydrogenation of the C5-C100 olefins (III), (VI), and/or (VII) can be selectively isomerized via a hydroisomerization process of such long-chain paraffins using one or more suitable hydroisomerization catalyst(s) (e.g., MSDW-3™ catalyst) to form isomerized products. Isomerized products can provide improved low temperature properties as compared to the products before isomerization.

[0125] In at least one embodiment, the C5-C200 olefins, such as the C5-C100 olefins (III), (VI), and (VII) are hydrogenated to hydrogenated polyolefin products, such as saturated products, such as C ₆ - C100 polymer products represented by Formula (VIII) or Formula (IX), such as C25-C50 polyolefin products, which optionally may conveniently be blended with one or more other components (e.g., additives) to produce, for example, a fuel composition (e.g., higher value diesel (cetane)), waxes, lubricant range products, and base stocks.

wherein:

Xis a one-atom to five-atom linkage (with a“one-atom” linkage referring to a linkage that provides a single, optionally substituted atom between the two adjacent carbon atoms, and a“five-atom” linkage, similarly, referring to a linkage that provides five optionally substituted atoms between the two adjacent carbon atoms);

Q is a one-atom to five-atom linkage. In at least one embodiment, and when the monomer is bicyclic (e.g., when R ¹⁶ and R ¹⁷ are linked), then Q is a one-atom or two-atom linkage, such as a linkage that has one or two optionally substituted atoms between the two carbon atoms to which Q is bound. For example, Q can be of the formula— CR ¹¹ R ¹² — (Q ^x )q’— wherein q’ is zero or 1, Q ¹ is CR ¹³ R ¹⁴ , O, S, or NR ^15’ , and R ¹¹ , R ¹² , R ¹³ , R ^14’ , and R ¹⁵ are independently selected from hydrogen, hydrocarbyl (e.g., C 1-C20 alkyl, C2-C20 alkenyl, C2-C20 alkynyl, Cs-C2o aiyl, C6-C24 alkaryl, C6-C24 aralkyl, Ci- C20 alkyl, Cs-C2o aiyl, C5-C30 aralkyl, or C5-C30 alkaryl), substituted hydrocarbyl (e.g., substituted Ci- C20 alkyl, C2-C20 alkenyl, C2-C20 alkynyl, C5-C20 aryl, C6-C24 alkaryl, C6-C24 aralkyl, C1-C20 alkyl, C5- C2o aryl, C5-C30 aralkyl, or C5-C30 alkaryl), heteroatom-containing hydrocarbyl (e.g., Ci- C20 heteroalkyl, C5-C20 heteroaryl, heteroatom-containing C5-C30 aralkyl, or heteroatom-containing C5-C30 alkaryl), substituted heteroatom-containing hydrocarbyl (e.g., substituted C1-C20 heteroalkyl, C5-C20 heteroaryl, heteroatom-containing C5-C30 aralkyl, or heteroatom-containing C5-C30 alkaryl); When q’ is 1, suitable examples of linkages can be wherein Q ¹ is CR ¹³ R ¹⁴ , thus providing a substituted or unsubstituted ethylene moiety to the cyclic olefin of Formula (IV). Accordingly, when R ¹¹ , R ¹² , R ¹³ , and R ¹⁴ are hydrogen, then Q is ethylene. When q’ is zero, the linkage can be substituted or unsubstituted methylene, and a suitable linkage within this group can be methylene (e.g., when R ¹¹ and R ¹² are both hydrogen);

one of R ⁷ and R ⁸ is hydrogen and the other is selected from hydrogen, hydrocarbyl (e.g., C1-C20 alkyl, C2-C20 alkenyl, C2-C20 alkynyl, Cs-C2o aryl, C6-C24 alkaryl, and C6-C24 aralkyl), substituted hydrocarbyl (e.g., substituted C 1-C20 alkyl, C2-C20 alkenyl, C2-C20 alkynyl, Cs-C2o aryl, C6-C24 alkaryl, and C6-C24 aralkyl), heteroatom-containing hydrocarbyl (e.g., heteroatom-containing C1-C20 alkyl, C2- C20 alkenyl, C2-C20 alkynyl, C5-C20 aryl, C6-C24 alkaryl, and C6-C24 aralkyl), or substituted heteroatom- containing hydrocarbyl (e.g., substituted heteroatom-containing C1-C20 alkyl, C2-C20 alkenyl, C2- C20 alkynyl, C5-C20 aryl, C6-C24 alkaryl, and C6-C24 aralkyl); and

[0126] Furthermore, hydroisomerization of the C5-C200 products, such as the C5-C100 products represented by Formula (VIII) or Formula (IX), such as C25-C50 polyolefin products, such as long- chain paraffins, can be performed using one or more suitable hydroisomerization catalyst(s) (e.g., MSDW-3™ catalyst; Pt/ZSM-48 catalyst; Pt/HZSM-5 catalyst; Pt/HY catalyst; Pt/SAPO-11 catalyst). Hydroisomerization of the C5-C200 products, such as the C5-C 100 products (VIII) can reduce the content of linear paraffins in hydrocarbon mixtures by producing branched compounds, and can enable the production of high-octane gasoline and low-pour-point diesel. The hydroisomerization of the C5-C200 products, such as the C5-C100 product represented by formula (VIII) can improve the viscosity properties of waxy feedstocks, for example.

[0127] In at least one embodiment, the hydroisomerization process is performed at a temperature of from about 15°C to about 300°C, such as from about 30°C to about 250°C, such as from about 50°C to about 150°C, alternalty from about 50°C to about 300°C; at a pressure of from about 15 psi (103.42 kPa) to about 1000 psi (6,894.76 kPa), such as from about 30 psi (306.84 kPa) to about 500 psi (3,447.38 kPa); for a reaction time of from about 3 minutes to about 20 hours, such as from about 4 minutes to about 10 hours, such as from about 6 minutes to about 2 hours; and/or w weight hourly space velocity (WHSV) of from about 0.05 h ¹ to about 20 h ¹ , such as from about 0.1 h ¹ to about 15 h ¹ , such as from about 0.5 h ¹ to about 10 h ¹ .

Lubricating Oils

[0128] Polyolefin products or hydrogenated polyolefin products of the present disclosure can be used as base stocks useful in engine oils. The polyolefin products and/or hydrogenated polyolefin products can be in the lube oil boiling range, such as from about 100°C to about 450°C, for example.

[0129] The viscosity -temperature relationship of a lubricating oil is an aspect often considered when selecting a lubricant for a particular application. Viscosity index“VI” is an empirical, unitless number which indicates the rate of change in the viscosity of an oil within a given temperature range. Fluids exhibiting a relatively large change in viscosity with temperature are said to have a low viscosity index. A low VI oil, for example, will thin out at elevated temperatures faster than a high VI oil. For example, the high VI oil can be recommended because of its higher viscosity at higher temperature, which can be translated into thicker lubrication film and better protection of the contacting machine elements.

[0130] In another aspect, as the oil operating temperature decreases, the viscosity of a high VI oil will not increase as much as the viscosity of a low VI oil. This is advantageous because the high viscosity of the low VI oil will decrease the efficiency of the operating machine. Thus high VI (HVI) oil has performance advantages in both high and low temperature operation. VI is determined according to ASTM method D 2270. A lubricating oil of the present disclosure can have a VI of about 120 or greater, such as about 140 or greater, such as about 150 or greater, such as about 170 or greater, such as about 180 or greater, as determined according to ASTM D2270.

[0131] VI is related to kinematic viscosities measured at 40°C and 100°C using ASTM method D 445. A lubricating oil of the present disclosure can have a kinematic viscosity at 100°C (KV100), as determined by ASTM D445, of about 2 cSt to about 25 cSt, such as from about 3 cSt to about 18 cSt, such as from about 4 cSt to about 10 cSt. Additionally or alternatively, a lubricating oil of the present disclosure can have a kinematic viscosity at 40°C (KV40), as determined by ASTM D445, of about 10 cSt to about 125 cSt, such as from about 20 cSt to about 50 cSt.

[0132] Polyolefin products or hydrogenated polyolefin products of the present disclosure can be present in a lubricating oil in an amount of from about 1 wt% to about 99 wt%, such as from about 1 wt% to about 50 wt%, such as from about 1 wt% to about 25 wt%, such as from about 5 wt% to about 10 wt%, based on the weight of the lubricating oil.

Other Lubricating Oil Additives

[0133] A lubricating oil of the present disclosure may additionally contain one or more lubricating oil performance additives including but not limited to dispersants, other detergents, corrosion inhibitors, rust inhibitors, metal deactivators, other anti-wear agents and/or extreme pressure additives, anti-seizure agents, wax modifiers, viscosity index improvers, viscosity modifiers, fluid-loss additives, seal compatibility agents, other friction modifiers, lubricity agents, anti-staining agents, chromophoric agents, defoamants, demulsifiers, emulsifiers, densifiers, wetting agents, gelling agents, tackiness agents, colorants, and others. For a review of suitable additives, see Klamann in Lubricants and Related Products, Verlag Chemie, Deerfield Beach, Fla.; ISBN 0-89573-177-0. Reference is also made to“Lubricant Additives Chemistry and Applications” edited by Leslie R. Rudnick, Marcel Dekker, Inc. New York, 2003 ISBN: 0-8247-0857-1.

[0134] Furthermore, the polyolefin products or hydrogenated polyolefin products of the present disclosure can be contacted/blended with one or more component s), such as any fuel additives (e.g., metal deactivators, corrosion inhibitors, lead scavengers, fuel dyes, and antioxidant stabilizers), to form a biofuel composition. Examples of such one or more additive(s) may include anti-oxidants, corrosion inhibitors, ashless detergents, dehazers, dyes, lubricity improvers and/or mineral fuel components, but also conventional petroleum derived gasoline, diesel and/or kerosene. The amount of additive(s) can range from about 0.1 wt% to about 10 wt%, such as from about 0.5 wt% to about 8 wt%, such as from about 1 wt% to about 6 wt%, such as from about 2 wt% to about 4 wt%, based on the total weight of the polyolefin products or hydrogenated polyolefin products blend.

Antioxidants

[0135] Suitable anti-oxidants may include phenolic anti-oxidants, aminic anti-oxidants and oil- soluble copper complexes. The phenolic antioxidants may include sulfurized and non-sulfurized phenolic antioxidants. The terms“phenolic type” or“phenolic antioxidant” used herein may include compounds having one or more than one hydroxyl group bound to an aromatic ring which may itself be mononuclear, e.g., benzyl, or poly-nuclear, e.g., naphthyl and spiro aromatic compounds. Thus “phenol type” may include phenol per se, catechol, resorcinol, hydroquinone, naphthol, etc., as well as alkyl or alkenyl and sulfurized alkyl or alkenyl derivatives thereof, and bisphenol type compounds including such bi-phenol compounds linked by alkylene bridges sulfuric bridges or oxygen bridges. Alkyl phenols may include mono- and poly-alkyl or alkenyl phenols, the alkyl or alkenyl group containing from about 3 carbons to about 100 carbons, such as from about 4 carbons to about 50 carbons, and sulfurized derivatives thereof, the number of alkyl or alkenyl groups present in the aromatic ring ranging from 1 to up to the available unsatisfied valences of the aromatic ring remaining after counting the number of hydroxyl groups bound to the aromatic ring.

[0136] A phenolic anti-oxidant may be represented by the general formula:

(R)x-Ar-(OH) 'y

where Ar is selected from phenyl, naphthyl, biphenyl, , and , where R is a C3-C100 alkyl or alkenyl group, a sulfur substituted alkyl or alkenyl group, such as a C4-C50 alkyl or alkenyl group or sulfur substituted alkyl or alkenyl group, such as C3-C 100 alkyl or sulfur substituted alkyl group, such as a C4-C50 alkyl group. Q is oxygen or sulfur y is at least 1 to up to the available valences of Ar. x ranges from 0 to up to the available valances of Ar-y. z ranges from 1 to 10, n ranges from 0 to 20, and m is 0 to 4 and p is 0 or 1. In at least one embodiment, y ranges from 1 to 3, x ranges from 0 to 3, z ranges from 1 to 4 and n ranges from 0 to 5, and p is 0.

[0137] Phenolic anti-oxidant compounds can be the hindered phenolics and phenolic esters which include a sterically hindered hydroxyl group, and these include those derivatives of dihydroxy aryl compounds in which the hydroxyl groups are in the o- or p-position to each other. Suitable phenolic anti-oxidants include the hindered phenols substituted with Ci+ alkyl groups and the alkylene coupled derivatives of these hindered phenols. Examples of phenolic materials of this type 2-t-butyl-4-heptyl phenol; 2-t-butyl-4-octyl phenol; 2-t-butyl-4-dodecyl phenol; 2,6-di-t-butyl-4-heptyl phenol; 2,6-di-t- butyl-4-dodecyl phenol; 2-methyl-6-t-butyl-4-heptyl phenol; 2-methyl-6-t-butyl-4-dodecyl phenol; 2,6-di-t-butyl-4 methyl phenol; 2,6-di-t-butyl-4-ethyl phenol; and 2,6-di-t-butyl 4-alkoxy phenol; and [0138] Phenolic type anti-oxidants in the lubricating industry may include commercial examples such as Ethanox® 4710, Irganox® 1076, Irganox® LI 035, Irganox® 1010, Irganox® LI 09, Irganox® LI 18, Irganox® L135.

[0139] The phenolic anti-oxidant can be present in a lubricating oil in an amount in the range of from about 0.1 wt% to about 3 wt%, such as from about 1 wt% to about 3 wt%, such as from about 1.5 wt% to about 3 wt% based on the weight of the lubricant oil.

[0140] Aromatic amine anti-oxidants may include phenyl-a-naphthyl amine which is described by the following molecular structure:

wherein R ^z is hydrogen or a Ci to Cu linear or C3 to C14 branched alkyl group, such as Ci to C10 linear or C3 to C10 branched alkyl group, such as linear or branched Ce to Cx and n is an integer ranging from 1 to 5, such as 1. For example, an aromatic amine anti-oxidants can be Irganox® L06.

[0141] Other aromatic amine anti-oxidants may include other alkylated and non-alkylated aromatic amines, such as aromatic monoamines of the formula R ¹⁹ R ²⁰ R ²¹ N where R ¹⁹ is an aliphatic, aromatic or substituted aromatic group, R ²⁰ is an aromatic or a substituted aromatic group, and R ²¹ is H, alkyl, aryl or R ²² S(0)xR ²³ where R ²² is an alkylene, alkenylene, or aralkylene group, R ²³ is a higher alkyl group, or an alkenyl, aryl, or alkaryl group, and x is 0, 1 or 2. The aliphatic group R ⁸ may contain from 1 to 20 carbon atoms, or can contain from 6 to 12 carbon atoms. The aliphatic group is a saturated aliphatic group. For example, both R ¹⁹ and R ²⁰ are aromatic or substituted aromatic groups, and the aromatic group may be a fused ring aromatic group such as naphthyl. Aromatic groups R ¹⁹ and R ²⁰ may be joined together with other groups such as S.

[0142] Suitable aromatic amine anti-oxidants have alkyl substituent groups of at least 6 carbon atoms. Examples of aliphatic groups may include hexyl, heptyl, octyl, nonyl, and decyl. For example, the aliphatic groups will not contain more than 14 carbon atoms. Suitable types of such other additional amine anti-oxidants which may be present include diphenylamines, phenothiazines, imidodibenzyls and diphenyl phenylene diamines. Mixtures of two or more of such other additional aromatic amines may also be present. Polymeric amine antioxidants can also be used.

[0143] Another class of anti-oxidant used in lubricating oil compositions and which may also be present are oil-soluble copper compounds. Any oil-soluble suitable copper compound may be blended into the lubricating oil. Examples of suitable copper antioxidants may include copper dihydrocarbyl thio- or dithio-phosphates and copper salts of carboxylic acid (naturally occurring or synthetic). Other suitable copper salts may include copper dithiacarbamates, sulphonates, phenates, and acetylacetonates. Basic, neutral, or acidic copper Cu(I) and or Cu(II) salts derived from alkenyl succinic acids or anhydrides may be particularly useful.

[0144] Such anti-oxidants may be used individually or as mixtures of one or more types of anti oxidants, the total amount used in a lubricating oil being an amount of from about 0.50 wt% to about 5 wt%, such as about 0.75 wt% to about 3 wt%.

Detergents

[0145] Detergents may be included in lubricating oils of the present disclosure. In at least one embodiment, a detergent is an alkali or alkaline earth metal salicylate detergent.

[0146] A detergent can be alkali or alkaline earth metal phenates, sulfonates, carboxylates, phosphonates and mixtures thereof. The detergents can have total base number (TBN) ranging from neutral to highly overbased, e.g., TBN of 0 to 500 or greater, such as 2 to 400, such as 5 to 300, and they can be present either individually or in combination with each other in an amount in the range of from 0 wt% to about 10 wt%, such as from about 0.5 wt% to about 5 wt % (active ingredient) based on the total weight of the formulated lubricating oil.

[0147] Other detergents can be calcium phenates, calcium sulfonates, magnesium phenates, magnesium sulfonates and other related components (including borated detergents).

Dispersants

[0148] During engine operation, oil-insoluble oxidation byproducts can be produced. Dispersants help keep these byproducts in solution, thus diminishing their deposition on metal surfaces. Dispersants may be ashless or ash-forming. For example, the dispersant is ashless. So called ashless dispersants are organic materials that form substantially no ash upon combustion. For example, non metal-containing or borated metal-free dispersants can be considered ashless. In contrast, metal- containing detergents discussed above may form ash upon combustion.

[0149] Suitable dispersants may contain a polar group attached to a relatively high molecular weight hydrocarbon chain. The polar group may contain at least one nitrogen, oxygen, or phosphorus atom. Suitable hydrocarbon chains may contain from about 50 carbon atoms to about 400 carbon atoms.

[0150] In at least one embodiment, a dispersant is an alkenylsuccinic derivative, produced by the reaction of a long chain substituted alkenyl succinic compound, such as a substituted succinic anhydride, with a polyhydroxy or polyamino compound. The long chain group constituting the oleophilic portion of the molecule which confers solubility in the oil, can be a polyisobutylene group. Exemplary U.S. patents describing such dispersants are U.S. Pat. Nos. 3,172,892; 3,219,666; 3,316,177 and 4,234,435. Other types of dispersant are described in U.S. Pat. Nos. 3,036,003 and 5,705,458.

[0151] Hydrocarbyl-substituted succinic acid compounds may be used as dispersants, such as succinimide, succinate esters, or succinate ester amides prepared by the reaction of a hydrocarbon- substituted succinic acid compound, such as those having at least about 50 carbon atoms in the hydrocarbon substituent, with at least one equivalent of an alkylene amine.

[0152] Succinimides can be formed by the condensation reaction between alkenyl succinic anhydrides and amines. Molar ratios can vary depending on the amine or polyamine. For example, the molar ratio of alkenyl succinic anhydride to TEPA can vary from 1 : 1 to 5 : 1.

[0153] Succinate esters can be formed by the condensation reaction between alkenyl succinic anhydrides and alcohols or polyols. Molar ratios can vary depending on the alcohol or polyol used. For example, the condensation product of an alkenyl succinic anhydride and pentaerythritol can be used as a dispersant.

[0154] Succinate ester amides can be formed by condensation reaction between alkenyl succinic anhydrides and alkanol amines. For example, suitable alkanol amines may include ethoxylated polyalkylpolyamines, propoxylated polyalkylpolyamines and polyalkenylpolyamines such as polyethylene polyamines, such as propoxylated hexamethylenediamine.

[0155] The molecular weight of the alkenyl succinic anhydrides may range from about 800 g/mol to about 2,500 g/mol. The above products can be post-reacted with various reagents such as sulfur, oxygen, formaldehyde, carboxylic acids such as oleic acid, and boron compounds, such as borate esters or highly borated dispersants. The dispersants can be borated with from about 0.1 moles to about 5 moles of boron per mole of dispersant reaction product.

[0156] Mannich base dispersants can be made from the reaction of alkylphenols, formaldehyde, and amines. Process aids and catalysts, such as oleic acid and sulfonic acids, can also be part of the reaction mixture. Molecular weights of the alkylphenols may range from about 800 g/mol to about 2,500 g/mol.

[0157] High molecular weight aliphatic acid modified Mannich condensation products can be prepared from high molecular weight alkyl-substituted hydroxyaromatics or HN(R)2 group-containing reactants. Examples of high molecular weight alkyl-substituted hydroxyaromatic compounds can be polypropylphenol, polybutylphenol, and other polyalkylphenols. These poly alkylphenols can be obtained by the alkylation, in the presence of an alkylating catalyst, such as BF3, of phenol with high molecular weight polypropylene, polybutylene, and other polyalkylene compounds to give alkyl substituents on the benzene ring of phenol having an average molecular weight of from about 600 g/mol to about 100,000 g/mol.

[0158] Examples of HN(R)2 group-containing reactants can be alkylene polyamines, such as polyethylene polyamines. Other representative organic compounds containing at least one HN(R)2 group suitable for use in the preparation of Mannich condensation products may include a mono- and di-amino alkanes and their substituted analogs, e.g., ethylamine and diethanol amine; aromatic diamines, e.g., phenylene diamine, diamino naphthalenes; heterocyclic amines, e.g., morpholine, pyrrole, pyrrolidine, imidazole, imidazolidine, and piperidine; melamine and their substituted analogs.

[0159] Examples of alkylene polyamine reactants may include ethylenediamine, diethylene triamine, triethylene tetraamine, tetraethylene pentaamine, pentaethylene hexamine, hexaethylene heptaamine, heptaethylene octaamine, octaethylene nonaamine, nonaethylene decamine, and decaethylene undecamine and mixture of such amines having nitrogen contents corresponding to the alkylene polyamines, in the formula H2N— (J— NH— ) _a H, mentioned before, J is a divalent ethylene and a is 1 to 10 of the foregoing formula. Corresponding propylene polyamines such as propylene diamine and di-, tri-, tetra-, pentapropylene tri-, tetra-, penta- and hexaamines can be also suitable reactants. The alkylene polyamines can be obtained by the reaction of ammonia and dihalo alkanes, such as dichloro alkanes. Thus, the alkylene polyamines obtained from the reaction of 2 moles to 11 moles of ammonia with 1 mole to 10 moles of dichloroalkanes having 2 carbon atoms to 6 carbon atoms and the chlorines on different carbons can be suitable alkylene polyamine reactants.

[0160] Aldehyde reactants useful in the preparation of the high molecular products useful in this disclosure include the aliphatic aldehydes such as formaldehyde (also as paraformaldehyde and formalin), acetaldehyde and aldol (b-hydroxybutyraldehyde). Formaldehyde or a form aldehyde- yielding reactant is exemplary.

[0161] Dispersants can include borated and non-borated succinimides, including those derivatives from mono-succinimides, bis-succinimides, and/or mixtures of mono- and bis-succinimides, wherein the hydrocarbyl succinimide is derived from a hydrocarbylene group such as polyisobutylene having a molecular weight of from about 500 g/mol to about 5000 g/mol or derived from a mixture of such hydrocarbylene groups. Other exemplary dispersants may include succinic acid-esters and amides, alkylphenol-polyamine-coupled Mannich adducts, their capped derivatives, and other related components. Such additives may be used in an amount of from about 0.1 wt% to about 20 wt%, such as from about 0.1 wt% to about 8 wt %, such as from about 1 wt% to about 6 wt % (on an as-received basis) based on the weight of the total lubricant.

Pour Point Depressants

[0162] Pour point depressants (also known as lube oil flow improvers) may also be present in lubricating oils of the present disclosure. Pour point depressant may be added to lower the minimum temperature at which the fluid will flow or can be poured. Examples of suitable pour point depressants include alkylated naphthalenes polymethacrylates, polyacrylates, polyarylamides, condensation products of haloparaffm waxes and aromatic compounds, vinyl carboxylate polymers, and terpolymers of dialkylfumarates, vinyl esters of fatty acids and allyl vinyl ethers. Such additives may be used in amount of from 0 wt% to about 0.5 wt%, such as from about 0.0001 wt% to about 0.3 wt%, such as from about 0.001 wt% to about 0.1 wt% based on the weight of the lubricating oil.

Corrosion Inhibitors/Metal Deactivators

[0163] Corrosion inhibitors are used to reduce the degradation of metallic parts that are in contact with the lubricating oil composition. Suitable corrosion inhibitors may include aryl thiazines, alkyl substituted dimercapto thiodiazoles, thiadiazoles and mixtures thereof. Such additives may be used in an amount of from about 0.01 wt% to about 5 wt%, such as from about 0.01 wt% to about 1.5 wt%, such as from about 0.01 wt% to about 0.2 wt %, such as from about 0.01 wt% to about 0.1 wt%, based on the total weight of the lubricating oil.

Seal Compatibility Additives

[0164] Seal compatibility agents help to swell elastomeric seals by causing a chemical reaction in the fluid or physical change in the elastomer. Suitable seal compatibility agents for lubricating oils may include organic phosphates, aromatic esters, aromatic hydrocarbons, esters (butylbenzyl phthalate, for example), and polybutenyl succinic anhydride and sulfolane-type seal swell agents such as Lubrizol® 730-type seal swell additives. Such additives may be used in an amount of from about 0.01 wt% to about 3 wt%, such as from about 0.01 wt% to about 2 wt%, based on the total weight of the lubricating oil.

Anti -Foam Agents

[0165] Anti-foam agents may be included in lubricant oils of the present disclosure. These agents retard the formation of stable foams. Silicones and organic polymers can be anti-foam agents. For example, polysiloxanes, such as silicon oil or polydimethyl siloxane, provide antifoam properties. Anti-foam agents are commercially available and may be used in conventional minor amounts along with other additives such as demulsifiers; usually the amount of these additives combined is about 1 wt% or less, such as from about 0.001 wt% to about 0.5 wt%, such as from about 0.001 wt% to about 0.2 wt%, such as from about 0.0001 wt% to about 0.15 wt%, based on the total weight of the lubricating oil.

Inhibitors and Antirust Additives

[0166] Anti-rust additives (or corrosion inhibitors) are additives that protect lubricated metal surfaces against chemical attack by water or other contaminants. One type of anti-rust additive can be a polar compound that wets the metal surface, protecting the metal surface with a film of oil. Another type of anti-rust additive can absorb water by incorporating it in a water-in-oil emulsion so that only the oil touches the metal surface. Yet another type of anti -rust additive chemically may adhere to the metal to produce a non-reactive surface. Examples of suitable additives may include zinc dithiophosphates, metal phenolates, basic metal sulfonates, fatty acids and amines. Other anti-wear additives may include zinc dithiocarbamates, molybdenum dialkyldithiophosphates, molybdenum dithiocarbamates, other organo molybdenum-nitrogen complexes, sulfurized olefins, etc. Such additives may be used in an amount of from about 0.01 wt% to about 5 wt%, such as from about 0.01 wt% to about 1.5 wt%, based on the total weight of the lubricating oil.

[0167] The term“organo molybdenum-nitrogen complexes” embraces the organo molybdenum- nitrogen complexes described in U.S. Pat. No. 4,889,647, which is incorporated by reference herein. The complexes can be reaction products of a fatty oil, dithanolamine and a molybdenum source. U.S. Pat. No. 4,889,647, which is incorporated by reference herein, reports an infrared spectrum for a reaction product of that disclosure; the spectrum identifies an ester carbonyl band at 1740 cm ^-1 and an amide carbonyl band at 1620 cm ^-1 . The fatty oils can be glyceryl esters of higher fatty acids containing at least 12 carbon atoms up to 22 carbon atoms or more. The molybdenum source can be an oxygen- containing compound such as ammonium molybdates, molybdenum oxides and mixtures. Other organo molybdenum complexes can be tri-nuclear molybdenum- sulfur compounds described in EP 1,040,115 and WO 99/31113 and the molybdenum complexes described in U.S. Pat. No. 4,978,464, which are incorporated by reference herein.

Diesel Fuels

[0168] In at least one embodiment, a diesel fuel is a C5-C200 hydrogenated polyolefin product, suhc as a C5-C100 hydrogenated polyolefin product, such as a C6-C25 hydrogenated polyolefin product.

[0169] The various types of carbon atoms of a polyolefin product of the present disclosure can be determined using 'H NMR spectroscopy. For example, di- substituted olefin content and tri-substituted olefin content are indicators of linearity of a polyolefin product. A high amount of di- substituted olefin content indicates high linearity, and a low amount of tri-substituted olefin content indicates high linearity. In at least one embodiment, a polyolefin product has a di- substituted olefin content of from about 30% to about 80%, such as from about 50% to about 75%, such as from about 60% to about 70%, based on total unsaturations of the polyolefin product. A polyolefin product of the present disclosure can have a tri-substituted olefin content of less than 50%, based on total unsaturations of the polyolefin product. In at least one embodiment, a polyolefin product has a tri-substituted olefin content of from about 1% to about 50%, such as from about 5% to about 40%, such as from about 20% to about 40%, based on total unsaturations of the polyolefin product. The high linearity of polyolefin products of the present disclosure provides improved cetane number, as compared to highly branched polyolefin products.

[0170] Diesel engines may operate well with a cetane number of from 48 to 50. Fuels with a lower cetane number have longer ignition delays, requiring more time for the fuel combustion process to be completed. Hence, higher speed diesel engines operate more effectively with higher cetane number fuels. A hydrogenated polyolefin product of the present disclosure can be used as a diesel fuel, as indicated by advantageous cetane numbers. For example, a hydrogenated polyolefin product can have a cetane number of about 30 or greater, such as about 40 or greater, such as about 45 or greater, such as about 48 or greater, such as about 50 or greater, such as about 60 or greater, such as about 70 or greater, such as about 80 or greater, such as about 90 or greater.

[0171] Gas Chromatography : For the dehydrogenation of alkanes, the produts were analyzed

using a GC (Agilent 6890 Plus) with an FID detector and a HP-PONA column (50 m length□ 0.2 mm diameter□ 0.5 Dm film thickness). The GC conditions were the following: Injector: 225 DC; 0.5 DL injection volume, 100/1 split ratio. Detector: 250DC. Oven: 35 DC (10 min), 2.5 DC/min to 135 DC, 10DC/min to 320 DC (6.5 min).

[0172] Spectra of products were recorded on a Bruker (400 MHz) spectrometer and referenced versus residual nondeuterated solvent shifts. The product samples were dissolved in chloroform-d or toluene-d ⁸ in a 5-mm O.D. tube.

[0173] ¹³ C-NMR: Spectra of products were recorded on a Bruker (400 MHz) spectrometer and referenced versus residual nondeuterated solvent shifts. The product samples were dissolved in chloroform-d or toluene-d ⁸ in a 5-mm O.D. tube.

Dehydrogenation of C2-C50 acyclic alkanes and C3-C50 cyclic alkanes in a heavy naphtha range.

[0174] Example 1 (FIG. 1). Dehydrogenation of n-heptane to heptenes using CuO

[0175] In a N2-filled glove-box, 0.5 g of CuO and 2.0 g of anhydrous n-heptane (Aldrich) were mixed in a 3 cm ³ Swagelok stainless-steel pressure cell. The cell was sealed and placed in an oven held at 275°C. After 3 hours, the cell was taken out and allowed to cool down to room temperature. The cell was then opened and the liquid product recovered and analyzed by GC (FIG.1). Example 1 demonstrates that the dehydrogenation of n-heptane using CuO as a catalyst, led to the formation of heptenes, here obtained as primary products. The GC analysis is shown in FIG.1.

[0176] Example 2 (FIG.2). Dehydrogenation of cyclohexane to cyclohexene using CuO

In an N2-filled glove-box, 0.5 g of CuO and 2.0 g of anhydrous cyclohexane were mixed in a 3 cm ³ Swagelok stainless-steel pressure cell. The cell was sealed and placed in an oven held at 275°C. After 3 hours, the cell was taken out and allowed to cool down to room temperature. The cell was then opened and the liquid product recovered and analyzed by GC (FIG.2). Example 2 demonstrates that the dehydrogenation of cyclohexane using CuO as a catalyst, led to the formation of cyclohexene, here obtained as primary product. The GC analysis is shown in FIG.2.

Ring-Opening Cross Metathesis (ROMP) of C2-C50 acyclic and C3-C50 cyclic olefins (Examples 3-7).

[0177] In a 20 mL glass vial, a solution of selected olefm(s) (1 mL each), toluene (5 mL), adamantane (internal GC integration standard), and ring-opening cross metathesis catalyst were added. The ring-opening cross metathesis catalyst used in Examples 3-6 is Ru-Grubbs 2 ^nd Generation Catalyst (5 mg). The ring-opening cross metathesis catalyst used in Example7 is heterogeneous Re catalyst (50 mg), activated with tetramethyl tin (3.5 mg). A heterogeneous Re catalyst was prepared by the incipient wetness impregnation method from NH4Re04 and aluminum oxide and calcined at 550°C for 3 hours. The results were analyzed by both GC and ¾ NMR.

[0178] Example 3(FIG. 3). Ring opening cross metathesis between cyclopentene and trans-4- octene. It was observed that with cyclopentene homo-metathesis, no oligomers were formed. However, only poly-cyclopentene was produced. The GC analysis demonstrates that the oligomers were formed when the two olefins were allowed to react with the Ru-Grubbs 2 ^nd Generation catalyst (FIG. 3), with a carbon number spacing of 5 carbons, thus due the cyclopentene ring.

[0179] Example 4(FIG. 4). Ring opening cross metathesis between cyclohexene and trans-4- octene. It was observed by GC analysis that the oligomers formed via ring-opening cross metathesis between cyclohexene and trans-4-octene were formed (FIG. 4). Under such reaction conditions, some olefin isomerization was observed. The major peak at C 14 is indicative of the coupling between the C8 trans-4-octene and the G, cyclohexene.

[0180] Example 5(FIG. 5). Ring opening cross metathesis between cyclohexene and 1-heptene. Analysis by both GC and ¾ NMR has shown that, in addition to the expected C13 product from the ring-opening cross-metathesis of 1-heptene and cyclohexene, it was observed that 1-heptene can homocouple in order to give 6-dodecene. The dodecene (or two 1-heptenes) can then couple to give a Ci8 product, which was demonstrated, and confirmed by GC analysis (FIG. 5).

[0181] Example 6(FIG. 6). Ring opening cross metathesis between mixed feeds (e.g., mixture of pentenes) using Ru-Grubbs 2 ^nd Generation Catalyst.

Mixed feeds, such as a mixture of Cs olefins including cyclopentene, were tested with Ru-Grubbs 2 ^nd Generation Catalyst. The GC analysis of Example 6 is shown in FIG. 6, and demonstrates a distribution maxima at C10 and C15, thus due to the cyclopentene ring opening metathesis.

[0182] Example 7 (FIG.7). Ring opening cross metathesis between mixed feeds (e.g., mixture of pentenes) using a heterogeneous Re catalyst.

Mixed feeds, such as a mixture of Cs olefins including cyclopentene, were also tested with a heterogeneous Re catalyst. Hence, the ring-opening cross metathesis reaction between a mixture of C5 olefins including cyclopentene was studied, and the GC analysis of Example 7 is shown in FIG.7. The distribution maxima at C10 and C15 are due to the cyclopentene ring opening metathesis.

Hydrogenation and Hydroisomerization of the C6-C100 olefins

The product from the metathesis reaction, 5.2 g, diluted with heptane was heated to 250°C in the presence of 2 g of the MSDW-3™ catalyst under 300 psi (2,068.43 kPa) of hydrogen for 6 days. Product analysis was conducted after hydroisomerization was carried out with MSDW-3™ catalyst, to demonstrate the production of lubricant range products with branched structures, with methyl branches (Example 8, FIG. 8, peak 8). ¹³ C-NMR spectra analysis of lubrication range products after hydroisomerization illustrates that the product displays a peak 1 at 5= 14 ppm corresponding to the methyl terminus, and a peak 8 at 5= 20 ppm, which correspond to the methyl branch.

[0183] Hydrogenation of ring opening metathesis product of cyclooctene was carried out using H2 at 250°C, followed by the hydroisomerization using MSDW-3™ catalyst (Example 9, FIG. 9). ¹³ C- NMR spectra analysis of lubrication range products after hydroisomerization between cyclooctene and 4-octene, illustrates that the product displays a peak 1 at 5= 14 ppm corresponding to the methyl terminus, and a peak 8 at 5= 20 ppm, which correspond to the methyl branch.

[0184] Example 10 (FIG. 10). Substituted cyclic olefins: Synthesis of 5-methyltridecane via Ring Opening Cross Metathesis between methyl-cyclopentene and 4-octene, and hydroisomerization.

[0185] The ring-opening cross metathesis reaction between a methyl-cyclopentene and 4-octene was carried out using Grubbs 2 ^nd generation catalyst, at 70°C and ambient pressure, for 1 day, resulting to the formation of a methyl branched-Ci4 polyolefin product. The methyl branched-Ci4 polyolefin product was hydrogenated, and the peaks labeled c5-Me+C8, were confirmed by GC-MS analysis (FIG. 10), illustrationg the production of 5 -methyl -tri decane.

5-methyltridecane

[0186] Overall, processes of the present disclosure provide C6-C100 polyolefin products including substituted and/or non-sub stituted olefins, from acyclic and cyclic olefins. Processes include converting hydrocarbons (such as heavy naphtha, including paraffins and/or naphthene-rich heavy virgin naphtha, such as C2-C50 cyclic and/or acyclic alkanes) to light distillates. The light distillate product includes the C6-C 100 polyolefin products, which produce, for example, a fuel composition (e.g., higher value diesel (cetane)) or waxes, lubricant range products, or base stocks when blended with one or more other components (e.g., additives).
